Fire-Derived Charcoal Along an Ecological Gradient in the Colorado Front Range
… C are in mineral soil pools in the predominant Colorado Front Range vegetation types. For the former, we combined fire model results for fuel consumption with published charcoal conversion constants to create maps of predicted charcoal C per fire. These maps represent the first spatial estimates …

Field delineation of geomorphic process domains along river networks in the Colorado Front Range
… of valley confinement, was evaluated for the Colorado Front Range by systematically following stream channels, categorizing them into stream type and process domain, and evaluating a number of channel geometry characteristics. The 111 reaches were then evaluated for significant differences in …

An assessment of streamflow production mechanisms for dam safety applications in the Colorado Front Range
… large historical storms and design storms in the Colorado Front Range and to propose methods to model these mechanisms that can be used by consultants. Hydrologic models were developed for five basins to simulate historical events in 1976, 1997, and 2013. The model results show saturation-excess …

Evaluating subalpine lake delta carbon storage in the Colorado Front Range and Washington Central Cascades
… deltas in the Washington Central Cascades and Colorado Front Range with the objectives of determining the magnitude of carbon storage and understanding the differences in storage between the two ranges. I used field, laboratory, and GIS techniques to determine the magnitude of and controls on …

Modeling Culex tarsalis Coquillett abundance on the northern Colorado Front Range using a landscape-level approach
… initial detection of West Nile virus (WNV) in Colorado in 2002, the northern part of the Colorado Front Range has come to be recognized as a high-risk area for WNV infections in humans, with 7.5% of the national cases of WNV being reported from Boulder, Weld and Larimer counties during …

The Effect of Mountain Pine Beetle Induced Tree Mortality on Home Values in the Colorado Front Range
… caused by deteriorating forest quality in the Front Range Counties of Larimer and Boulder Colorado. We employ a repeat sales model that allows for region specific price indices, and non-linear age-related depreciation in home values. We use the time-invariant existence of pine forest near a …

Snowmelt and rainfall runoff in burned and unburned catchments at the intermittent-persistent snow transition, Colorado Front Range
… are the dominant sources for streamflow in the Colorado Front Range, and wildfire can greatly affect the hydrologic regime through which these inputs are delivered to the stream. However, the specific changes to the hydrologic processes that drive runoff production made by wildfire are not …

How do ecological restoration treatments affect understory plant communities in dry conifer forests of the Colorado Front Range?
… plant communities in dry conifer forests of the Colorado Front Range using a Before/After/Control/Impact study design. We collected data at 1-2 years pre-treatment, 1-2 years post-treatment, and 4-6 years post-treatment in 156 plots distributed across 8 sites, encompassing 15 treatment units and …

Modeling hydrologic processes associated with soil saturation and debris flow initiation during the September 2013 storm, Colorado Front Range
… produced more than 1,100 debris flows in the Colorado Front Range, about 78% of which occurred on south-facing slopes (SFS). A few previously-published soil moisture observations suggest that SFS were wetter than north-facing slopes (NFS) during the event, which would contrast with soil …

Geochemical modeling-based prediction of water-rock interaction during aquifer storage and recovery utilizing selected Colorado Front Range aquifers
This study characterizes the Fountain Formation, Ingleside Formation, and sandstones of the Dakota Group and considers the potential of these three formations as hypothetical Aquifer Storage and Recovery (ASR) targets. Compositional data from surface rock samples, including major, minor and trace …

Wildfire and development : why stronger links to land-use planning are needed to save lives, protect property, and minimize economic risk
Exploding growth along the Colorado Front Range has expanded the wildland-urban interface-the area where homes and vegetation mix. This area, known as the WUI, is at high risk of wildfires. Wildfire risk is based on both natural conditions, such as invasive species and climate change, and human …

Effect of latent heating on mesoscale vortex development during extreme precipitation: Colorado, September 2013
… funneled unseasonal amounts of moisture to the Colorado Front Range, resulting in extreme precipitation and flooding. The heaviest precipitation during the September 2013 event occurred over the northern Colorado Front Range, producing a 7-day total of over 380 mm of rain. The flash flooding …

Prehistoric land use, site placement and an archaeological legacy along the foothills of the Colorado Northern Front Range
This research takes place in the Colorado Front Range foothills in Northern Colorado. Previous artifact collections were recovered in past decades from sixty-six prehistoric sites and isolated finds within a bounded geographical area that includes the Dakota and Lyons hogbacks west of the city of …
